Visited an area in England called Lulworth Cove and Stair Hole where the
sedimentary rocks are almost verticle.
So this got me wondering, on the Richter Scale (if it goes up this high)

theories, and am attempting to publish a paper on this.  I notice that
several threads on this have appeared in this group lately. I've tried
to read through them, but find it difficult since many posters quote

Why?  There are over three hundred thousand of them (on plate
tectonics) already.

A google group search for the terms "Schoch" and "Sphinx" turned up only a
few documents on this group, the newest being from four years ago, so I
feel reasonably confident that I am not awakening a tired thread which is
discussed ad-nauseum on this group, but if you disagree, ...

Anyone have a comment on this:
"Recent research indicates that five or more catastrophic floods up to
around a thousand feet deep roared through the Grand Canyon.  These were
released by the catastrophic rupture of landslide and lava dams over the

Where does the new land from mid-Atlantic ridge go?
Does the new land being created in the mid-Atlantic ridge subduct under
the east coast of the Americas and west coast of Africa?  Or is the
pressure relieved by the Pacific Ocean boundary?

The Geological Society of America just published a new geology
map of North America ($125), the first since 1965.
I heard the compiler talk about it last week.
The overall outlines of the land geology are the similar,

Hi All...
A real geology question from a non-geologist (but interested layman).
Welded tuffs have piqued my interest of late.  I managed to track down
the author of a graduate thesis on the geology of the area right around
